WebUnder the hood, to prevent reference cycles, PyTorch has packed the tensor upon saving and unpacked it into a different tensor for reading. Here, the tensor you get from accessing y.grad_fn._saved_result is a different tensor object than y (but they still share the same storage).. Whether a tensor will be packed into a different tensor object depends on … WebNov 7, 2024 · As you can see, each individual entry is a tensor requiring gradient. Of course, the backpropagation does not work unless a pass in a tensor of the form tensor([a,b,c,d,..., z], grad_fn = _) but I am not sure how to convert this list of tensors with gradient to a tensor of a list with a single attached gradient.
